In other words, the returned object is exactly what you'd get if you did:
a = new Array;
a.__proto__ = [some type].prototype;
[some type].prototype.__proto__ = Array.prototype;

For what it's worth, at least some JITs deoptimize |a| if you do that. 
We'd probably need to do something to make sure that _doesn't_ happen in 
this case, right?
